GEORGE C. RITTENHOUSE, OF GLENSIDE, PENNSYLVANIA.

EXHAUST-HEAD.

Specification of Letters Patent.

Patented Nov. 1'7, 1908.

Application filed April 3, 1908. Serial N o. 424,987.

To all whom 'it may concern:

Be it known that I, GEORGE C. RITTEN- HOUSE, a citizen of the United States, residing at Glenside, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Exhaust-Heads, of which the following is a specification.

This invention relates to the construction of exhaust-heads, especially of such as are used in connection with highly heated exhaust steam, and in which a large area of cooling 'surface is essential to reduce the steam to the point of condensation.

The object of my invention is to provide a construction of the exhaust-head of especially simple and compact form, which is readily attachable to an exhaust pipe and which will provide for an increased area of cooling surface and a free circulation of atmospheric air in horizontal planes through the exhausthead as to provide for the expeditious condensation of highly heated steam to relieve the exhaust pipe of back pressure.

The nature' of my improvements will be best understood as described in connection with drawings in which they are illustrated and in which Figure l is a perspective view of an exhaust-head embodying my invention. Fig. 2 represents a vertical section of the device taken on a line 22 of Fig. l. Fig. 3 shows a horizontal section of the same taken on a line 3 3 of Fig. 2, and Fig. 4L is a side elevation of an exhaust-head embodying my invention.

A, indicates the shell of the exhaust-head which is preferably cylindrical in shape and which is furnished with a conical base A1, fitted with exhaust connections which comprise a fitting A2, to receive the exhaust steam pipe and a fitting A3, to receive a drain pipe. The shell A, is provided with openings a, a, etc. to receive the ends of air cooled condensing tubes B, which may be rectangular in cross section as illustrated in Figs. 1, 2 and 3 of the drawings or circular as illustrated in Fig. 4. Several of the tubes B, are centrally connected within the shell and form a group of tubes having a central line of communication within the exhaust-head. Two or more groups or clusters of these air cooled tubes B, are arranged in juxtaposition within the shell A, presenting superposed clusters of tubes horizontally disposed throughout the exhaust-head. The top of the shell A, is provided with a conical cap C, having a central discharge opening C1, to receive a perforated pipe G2, which as shown in Fig. 2 isinterposed between said cap and the uppermost layer of cooling tubes. The pipe C2, by reason of its location acts as a final chill to the partially condensed steam as also a screen to arrest and dispose of a portion of the condensed vapor.

As illustrated in Fig. el, a cluster of air cooled condensing tubes B, is arranged about a central drum B1, which forms a medial line of communication for all of the tubes of the cluster and which may, if desired be in communication with the adjacent drum B1, of the superposed series, in which case there would be formed a line of communication with all of the tubes of the exhaust-head.

In operating the device, the exhaust fluid enters through an exhaust pipe I) (indicated hy dotted lines) and is carried in the direction of the arrow against a cone or spreader D1, by which its course is gently diverted causing the fluid to enter the path of the first cluster of air cooled condensing tubes.

As the tubes of the superposed clusters or series are staggered or out of alinement the fluid will pursue a zigzag course through the space between the tubes causing the precipitation of much of its vapor as it is met by and impinges upon the numerous tubes which together with shell or casing of the exhausthead constitutes a broad area of cooling and condensing surface. Impinging upon and reacting from the cap C, the expanded vapor will pass through the perforations in the pipe C2 and through the openings C1 of the cap to the atmosphere.

Having described my invention what I claim and desire to secure by Letters Patent is:

l. An exhaust-head comprising an outer shell provided with exhaust connections, a plurality of radially disposed tubes located within the shell and adapted to contain air, and a cap to said shell provided with a centrally located discharge opening.

2. An exhaust-head comprising in combination with the outer shell and exhaust connections, a plurality of tubes arranged in a horizontal plane and connected together within the shell, and a cap to said shell and adapted to convey air provided with a centra-ily disposed discharge opening.

3. An exhaust head comprising an outer shell provided with exhaust connections, ra-

dially disposed and centrally Connected Cooling tubes arrangedin su'perposed layers Withv in the casing forming passages for air, and

a eap joined to the shell and provided with,

a central discharge opening.

4. In combination With'the shell or an exhaust head, a plurality of radially disposed ,and adapted to containair, a cap provided with a central disehargeopening anda iperoratedtube adaptedlt'o said opening anc 1n- {terposed betvveenthe cap and-the uppermost layer of cooling-tubes.

ladapted to contain air arranged Within the shell and connected to or forming part 'or' a rcentral easing or hub, a Cap provided with a central discharge opening and a perforated tube adapted to said opening Within the shell. In testimony whereof I affix niy signature in preseliee 'of two Witnesses.
